i have a 94 coup and whenever i go over 55 the front left side of my car shakes bad. i have had all my tiers balenced and they seemed to be fine. still have no clue why it is shaking plz help!

 

Axle bent? Front wheel bearing? Ball joint? Tie rod? Jack it up and see if anything is loose or out of the ordinary..

 

Alignment?

 

alignment doesnt cause shaking. check ur axle its most likely bad. I have the same problem in my del sol just havent taken the time to change it. but i suggest checking everything else while u have the car in the air. shouldnt take more than 5-10 mins

 

Don't tell me it doesn't. Shaking, vibration, whatever you want to call it. I have had many times where I get this slightly after hitting a pothole and an alignment fixed it.

 

mabye after hitting a pothole not havin your toe setting correct will casue some irregular vibrations but you wont feel vibrations from a alignment issue while driving straight down the street at 55 mph

 

Right. I have no idea what I'm talking about. How do you have vibration and not feel vibration? That makes no sense.

 

alignment can cause a shaking, especially with caster shifted more negatively. ive seen it, felt it, know it.

also, check rims for bends and tires for shifted belts (they WILL balance fine but still shake)
check for loose or worn suspension components (BJs, bushings etc)
check for hub/rotor runout (does the brake pedal pulsate when you hit the brakes?)
axles loose / too much play / not straight

and if you don't feel comfortable checking this yourself, bring it to the dealer.

 

If you are feeling the shaking starting at 55, and slowly fades after 70, check the inner cv joints on the axle. Dont trust a good looking rubber boot. Your problem could be the same as mine.

 

Bad wheel bearing or warped rotors, just a thought.

 

How bad is the shaking? Could you feel it only on the steering wheel,only on the body, or both body and steering wheel?

 

it starts to shake slowly at 50 then as i go faster it gets to the point that it shaked the whole car bad and i dont even want to try to push 70 because the shaking is so bad around 60 to where i have to pull off to the side of the road beacuse i feel like im going to crash lol

 

i did take it to Les Schwab and they said that my wheel bearing has some dust in it. they also said that it had around 1mm of room to move around and they said that would not make my car shake. That is the only thing they said.

But when i looked at it befor i took it there i noticed that my axle bold was loose so i fixed that but it still shakes.

 

Lift the front of the car. Provide jacks or whatever on the lower control arm near to tires as possible.One tire at a time. Be sure the tires can rotate freely. Run the engine and put into gear up to the speed were the shaking starts. have somebody step on the gas and look at the gauge. While you look around and see where the wobbling,shaking, vibration is coming from. If shaking is intense on the body but not too much on the steering wheel, keep an eye on the CV joints. Do this to both sides. If the shaking is still not found, atleast you have narrowed down the area to search for. It worked for me though.

 

lower control arm bushings, the ones that connect the arm to the car.
